Overview

The CORSA Performance 21042BLK is a Sport Cat-Back Exhaust system with black tips, designed for a true muscle car sound with deep resonance during acceleration. It features patented Reflective Sound Cancellation (RSC) Technology to provide aggressive sound under acceleration while eliminating drone during cruising. The straight-through design reduces back pressure, increasing engine proficiency, horsepower (+5 HP), and torque (+4 TQ), with a 48.35% increase in airflow compared to stock. The system also offers a weight reduction of 4 lbs.
